To aZZwhom it may concern: 3

\ Be it known that I, ANTHONY SoArloomo. a citizen of the United States,residing at Arlington, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in'Adjust ableQuadrats for. Printing-Presses, of"

which the following is afull, clear, and we act specification. V

This invention relates to printing presses. and especially to means forsupporting cards or blanks in proper position on thetympan of the platento insure the impression being" made straight on said card or blank.

It is the aim of theinvention to provide supporting means of thiskind,to be hereinafter called quadrats, which are adjustable to bring thecard or blank into eXactparallel relation to the type, irrespective ofthe precise positions of said quadrats on the tym pan. Consequently,when'this invention is used, it is not necessary to place the qu adratsso carefully on the tympan, and once placed it is not necessary to movethem but simply to adjust them in order to accommodate the card or blankto an uneven or slightly inclined line ti type. a

The invention will be first hereinafter described in connection with theaccompanying drawings, which constitute part of this specification, andthen more specifically de-. fined at the end of the description. v

In the accompanying drawings, wherein similar reference characters areused to designate corresponding parts throughout the several viewsFigure 1. is a plan view of a part of the tympan of a platen of aprinting press,

showing a pair of the adjustable quadrats mounted thereon andsupportinga card.

Fig. 2 is a section on the line IIII of Fig. 1, on an enlarged scale,and

Fig. 3 is an enlarged: detail view of'one of the quadrats.

In Figs. 1 and 2, I designates the platen and 2 the tympan or cover ofpaper or cloth thereon. Each of thequadratscomp-rises a body portion 3having, a central recess 4 in which is loosely fitted a millednut 5. Ahead member 6 is rigidlymounted on one end of a screw-threaded pin 7which passes loosely through the body portion 3 about centrally oft-herecess 4: and operatively engages in the nut 5. Rotation of the nutwill,

therefore, move or adjustthe screw rod. or I Gopies of this patent mbeobtained m r 'specificationof lietters Patent.

the screw pin outside of the body portion 'andacts as a lock for holdingthe pin in adjusted position by being turned up against said body. a

The body portions of the quadrats are de: signed to be glued orotherwise secured to the face of the tympan 2 as illustrated in Inorderto insure the head pin '7 an dhead 6 with'respect to thebody member3.. -Another nut '8 is mounted on the card 10 from working down betweensaid head and tympan, a thin flangeor lip 12 isformed on said headprojecting therev from and is inserted inaslit 11, Fig. 2, in"

The quadrats are preferably used in pairs,

as shown in Fig. 1 so that'one end of the card 10 1nay be raised orlowered with respect to the other in order to bring the/card as a,wholein' proper parallel relation to the type .(not shown). More orlessof the quadrats may, however, be used asmay be necessary or desirablewithout departing from thisinvention- Y j 7 Having thus described myinvention, what I I claim as new and desire to secure "by Letters Patentof the United States is:-

1. In a device of the character described,

the combination with the tympan of a print ing press platen, said tympanhaving a .slit 7 therein,v of a card supporting, device comprising abody portion secured to the tympan, a head for engaging the card, saidhead having a fiangeextending its full width and engagingthe slit inthetympan sothat the outeredge of said flangeis covered by saidtymp'an,and means foradjusting the head with respect to the body. i 1

2. In a device of the characterdescribed,

the combination with a tympan of a print- "ing press platen, said tympanhaving a slit v therein, of a card-supporting device comprising a bodyportion secure'd'to the tyme pan, ahead forengagingthe card, and a"flange extending the full "width of the :head

and engaging the slitin the tympan so that the outer edge of said flangelsicoveredfby said tympan. means for gradually: moving the head withrespect to the body for making fine adjustments, and means for lockingsaid headin adjusted position.

In testimony whereof I have signed my nanie to this specification.,
